Yes, he is right, all small journal cranks I've ever seen (67 and older) never had a bolt.
My one concern with pounding it on is that the thrust bearing on the crank takes all the abuse when you do it that way. I know guys do it but to me it's scary.
Is the engine in the car? When I rebuilt my 327 years ago I stood the engine up on end on the floor so that the back of the crank was supported and then tapped it on.
I think the factory service manual even shows that you can do it with a block of wood as you say though.

A good idea to drill and tap them and use a bolt. I'd try to install using a hammer and a piece of wood and gentle persuasion if you don't go that route. Don't hammer on the outside ring at all.

There is a tool that both removes and installs harmonic balancers. I borrowed it from a friend for the last 350 I assembled and it got the balancer 3/4 of the way on. A piece of 2"x4" and one shot with a big hammer got it the rest of the way.
Carl I like your idea of putting it on its end and than hammer it on,,as its on the stand right now,scary to think it might come off driving so drilling and tapping a bolt hole would make me feel a little less worryed but getting it centered for me is scary also,,,Thanks guys
ok next I know its internally balanced My Factory pistons have stamped single numbers in their centers left bank ..9.9.0.9....right bank 9.11.9.9...are these because of different weights ? to make it balance...if so buying after market pistons ..would I need to get it all balanced with crank ..?
The 67 283 I have has the cranked threaded for a bolt but no bolt. I do not know the history Of the engine . The hole was full of dirt and grease and looks like it never had a bolt. Noticed it threaded when I cleaned out the centre of the crank snout. Could it be stock.

I saw one also, but probably thirty years ago. The balancer didnt have a bolt but it was threaded. I thought a rebuilder may have drilled and tapped it as the crank was .010/.010. Also this crank was cast iron, not forged steel.

my 327 has only the TDC grove line in the balancer no other marks for before or after timing ? dont make sence to me ? going to be hard to set timing with my new L79 cam..I will check again with my glasses on but I really dont see any other markings ?...good news is my balancer as a center punch so I should be able to drill and tap a bolt
There should be a timing cover tab with all the markings on it Bill.
x2 Markings will be on the cover tab. Just make sure it is spot welded...not a bolt on tab. Pretty sure they were all spot welded to the cover back then.....bolt ons can change your timing. Can also throw it in the oven at 350 if not bolting on. Will expand and be a lot less effort to pound on the crank.
